If louder noises dont bother you and you were able to inspect the car you are good to go. Taking muffler out makes:'
- car lighter
- reduses the back pressure
- increses engine noises
- Aerodynamic wise it depends did the muffler smooth the underside of the car or not. I would also put some pipe to extend the pipe to the rear part of the car. If there is pipe under the car you can get fumes inside the when being stationary...
